Biography
Donal Henry was born in Saltley, Birmingham, England in 1886, and he belonged to the sizeable Irish diasporic community in the city. He became a member of the IRA, serving as one of their operatives on British soil during the Anglo-Irish War. During the Irish Civil War, he sided with the anti-treaty faction, and he was sent to infiltrate the pro-treaty IRA by working alongside Irene O'Donnell. He loathed the Peaky Blinders leader Tommy Shelby and had trouble holding back his anger at meetings with him, although he and O'Donnell ultimately convinced him to assist them and Inspector Chester Campbell with their assassination plan for Field Marshal Henry Russell. Shelby later discovered that Henry was a spy, and he told Campbell that he would have to kill Henry as a precondition for his involvement in the murder. Campbell had his men execute Henry and place his body in a heap of coal, and Shelby then agreed to go along with the plot.
